Zoom Softkey
The Zoom softkey will only appear if a capnogram is currently displayed. Select the full scale
range for the displayed capnogram by scrolling among the different zoom levels. Zoom levels
change with each press of the Zoom softkey. They are as follows:

•
0-25 mmHg

If the unit is using kPa or %, the scales are 0-1.7, 0-3.3, 0-6.6, 0-10, 0-13.3, and 0-20.0. (Refer
to the R Series Configuration Guide for instructions on how to configure alternate units of
measure.)
Average Softkey
The R Series unit provides 3 different time periods over which EtCO
2
values are averaged: 1
breath, 10 seconds (default), and 20 seconds.
The user can select the averaging period by pressing the Average softkey. When the Average
softkey is pressed, the unit displays the selections.
Press the 1 breath, 10 secs or 20 secs softkey for the desired time period.
Press the Return softkey to return to the main menu.
Comp. Softkey
The R Series unit can compensate for elevated levels of oxygen and/or the presence of nitrous
oxide. Oxygen compensation should be activated when oxygen levels in excess of 60% are
present in the airway circuit. Nitrous oxide compensation should be activated when nitrous
oxide is present in the airway circuit. If the concentration of oxygen in the breathing circuit
exceeds 60% and nitrous oxide is in use, both O
2
and N
2
O should be activated.
When the Comp softkey is pressed, the unit displays the None, O2, N2O, O2&N2O, and
Return softkeys.
